SKT672-060-E

Ordering number : EN7441B STK672-060-E Thick-Film Hybrid IC Unipolar Constant-current Chopper (external excitation PWM) Circuit with Built-in Microstepping Controller Stepping Motor Driver (sine wave drive) Output Current 1.2A (no heat sink*) http://onsemi.com Overview The STK672-060-E is a stepping motor driver hybrid IC that uses power MOSFETs in the output stage. It includes a built-in microstepping controller and is based on a unipolar constant-current PWM system. The STK672-060-E supports application simplification and standardization by providing a built-in 4 phase distribution stepping motor controller. It supports five excitation methods: 2 phase, 1-2 phase, W1-2 phase, 2W1-2 phase, and 4W1-2 phase excitations, and can provide control of the basic stepping angle of the stepping motor divided into 1/16 step units. It also allows the motor speed to be controlled with only a clock signal. The use of this hybrid IC allows designers to implement systems that provide high motor torques, low vibration levels, low noise, fast response, and high-efficiency drive.
